Exoplanets with masses error and radii error less than 25%. Symbol size is proportional to mass. Colors correspond to equilibrium temperatures calculated with bond albedos of 0.3 and redistribution factors

Keith’s note: this just came out of my head as a stream of inter-related events. Some times I feel like Forrest Gump. Other times I am in Luke Skywalker mode.

Overview of the chemical elements detected in the transmission spectra of Ultra-Hot Jupiters (UHJ). Planets are ordered by decreasing equilibrium temperature. WASP-33 b is a more challenging target due to

The HPF-SpecMatch spectra fit results for order index 5. Top: two plots showing the five best-fit stars (red) selected to compose the spectra. The size and transparency of these five

Displaying the sudden change in spectral features for oxygen-rich atmospheric spectra. Type B atmospheres spectra do not show any CH4 features, as do type C which are extremely oxygen-rich. Both
